Three possible causes ,
1. Water leak from outside
2. leaking heater core
3 .air conditioning evap drain plugged
If you eliminate 2 & 3 you can go after #1.
If the heater core is leaking, the coolant level should be dropping and you might get a sweet smell of anti freeze when you operate the heater.
If you used the defrosters or the air conditioning recently and the moisture that collects on the evaporator core cannot drain because the drain is blocked with trash
If the portion below the wipers (Cowl) , has an opening where rain water can enter.it will accumulate under the floormat
If you rent a coolant system pressure tester you can double check if the heater core is leaking.

A leaking heater core will fog up your windshield especially when the defroster is used. Even the slightest leak. Loose/ leaking heater hose connections sometimes can allow some coolant into the passenger compartment. There will be an unpleasent odor noticed in both cases. Since you didn't mention anything else, I would suspect a leak from outside. Spraying lightly with a hose in certain areas may show your leak source.You may have to peel the carpet to look at the floor pan area and to let that dry out before rust sets in..
